Introduction of Caterpillar Type Hydraulic Tunnel Drilling Device
ZDY—L Caterpillar Type Hydraulic Tunnel Drilling Device (omnidirectional type)is kind of power-head drilling device, which belongs to the automatic type，large torque, and wide range of rotating speed of drilling machine.
The tunnel drilling rig is suitable for the drilling hole works that 360°horizontal and ±90°vertical along the tunnel. It can meet various needs of drilling, such as the holes of the geological exploration, methan drawing out, water injection and other engineering holes.
Features of Caterpillar Type Hydraulic Tunnel Drilling Device
The tunnel drilling rig machine mainly consists of three parts: the main engine, pump station, and the operation panel.
It has the features of whole layout, compact structure and convenient operation. It has advantages of advanced technical performance, strong applicability and fast moving.
